What we'd really like is something like:
/* foo.h */
#ifndef _FOO_H
#define _FOO_H
#define _FILE_REF __fileref_foo_h
[...]
#undef _FILE_REF
#endif /* _FOO_H */
... and have an automatically generated library (.a file) with all these
strings that could be pulled in as necessary -- but only one instance of
each. However, doing this without compiler support seems ugly in the
extreme.
Of course, if the linker would fold strings for us then it would be a
helluva lot easier...
